Overview
Rb025f1-16p31y36e-zs ball valveFrench connection, pn 16/25 kg pressure, piston-type aerodynamic implementer, which is a rotary-type cut-off valve, which is generally used in combination with aerodynamic elements, such as an electromagnetic valve, for the execution unit of the gaseous unit combination table. The valve structure consists of soft-sealed valves and full metal valves, which are used at both constant (-40 ~180 °c) and high temperatures (-60 ~ 450 °c). The product has high speed, thrust, high sealing performance, high rated flow coefficients and high turnover of parts. As a result, gas, liquid pipeline intermediates, which are widely used in production sectors such as oil, chemical, pharmaceutical, metallurgical, light-swipe, paper, sewage, etc., are cut off or opened, so that the production process can proceed according to certain procedures. It consists mainly of aero-pistol executives and cut-off valves, which can also be configured between the executing agency and the cut-off valve, depending on user needs。
Structural rationale
Rb025f1-16p31y36e-zs ball valveGenerally used in combination with attachments such as electromagnetic valves, limit switches, aerodynamic implementers such as gt, at, with high output power, mobility sensitivity, effective opening and disconnection. Its cylindrical perforate valve core has a cut function, which is second only to the control of viscous media such as fibres and particles。
Characteristics
1 the fluid resistance is small and the ball valves are small in the valves, even if they are indented。
2. Interpolation bearings reduce the grinding rectangles of valves, allowing them to operate smoothly and flexibly over the long term。
3. Valve seals are in good condition, with seals made of flexible materials such as polytetrafluoroethylene, with a structure that is easy to seal, and valve capacity increases as the pressure of the medium increases。
4. Valves are securely sealed, and since they operate as if they were moving, but do not act as lifts or lifts, the fillings of the valves are not easily sealed and their capacity increases with the pressure of the medium。
5. The life of the ball valve is long due to the good self-fluorinated material such as polytetrafluoroethylene and the low losses of friction with the sphere。
6. Lower valves and head bumps of valves prevent the vents from ejecting, e. G., if a fire results in the sealing of the poles, metal contact may also be formed between them to ensure that the valves are sealed。
7. Electrostatic function: the placement of springs between the sphere, valves and valves allows the export of electrostatics from the switch process。
